They make their way through the narrow aisles of the crowded department store, picking up a sweatshirt here, trying on a baseball cap there, checking out the endless array of merchandise that bears the Harvard University insignia.
Watching Murphy, you can well imagine the Co-op’s found- ers, who started the store in 1882, peering through the tiny win- dowpanes to keep an eye on the shop floor. Was the Harvard
Square store attracting steady traffic? Were the college students buying enough books and supplies for the Co-op to make a profit?
Back then, it was tough to answer those questions precisely. The owners had to watch and wait, relying only on their gut feelings to know how things were going from minute to minute.
Now, more than a hundred years later, Murphy can tell you, down to the last stock-keeping unit, how he’s doing at any given moment. His window on the business is the PC that sits on his desk. All day long it delivers up-to-the-minute, easy-to-read elec- tronic reports on what’s selling and what’s not, which items are running low in inventory and which have fallen short of forecast. In a matter of seconds, the computer can report gross margins for any product or supplier, and Murphy can decide whether the margins are fat enough to justify keeping the supplier or product on board.

$55 million business.
